ABSTRACT:
A rotatable disc having an annularly arranged screening zone includes a plurality of like cavities separated by spacing webs. A housing for the disc includes a first plate with a front and rear side and a second plate with a front and rear side. The disc is rotatably mounted between the rear side of the first plate and the front side of the second plate. A first flow-through bore in the first plate has a front side and a rear side and a second, aligned flow-through bore in the second plate also has a front side and a rear side. The disc is mounted in the housing such that at least one of the cavities is in alignment with the first flow-through bore and the second flow-through bore, the first flow-through bore, the second flow-through bore and the at least one cavity forming a flow-through channel. The second flow-through bore has a preselected outer contour at the front side thereof. The first flow-through bore includes a flow-shape forming means for causing the contour of a cross-section of the molten flow at the rear side of the first flow-through bore to correspond with the pre-selected outer contour.
